Why is it useless to send 66 SMS status reports?

Thank you for inviting me! Bian Xiao suggested here that the landlord should calm down and solve the problem. If you encounter problems here, you can only get your own courier as soon as possible!

This happened to Bian Xiao. When you send a text message to someone, you are prompted that it failed to be sent, or it was sent in the past. The other party said I didn't receive it. An innocent look! And you have a hundred thousand reasons in your heart, "How could it be that I didn't receive it? It's obviously from me. You are lying to me ... ",in addition to the fact that we often know that the mobile phone is in arrears and the signal is not good, there are several reasons that lead to the failure of SMS sending:

1, the information center number is set incorrectly;

2. Labor is not audited in time;

3. There is something wrong with the short message, and it has been returned or is waiting to be returned;

4. The mobile phone receives SMS interception or blacklist;

The process of sending short messages

(1) In the state of editing and submitting short messages, if the number of the short message service center is set incorrectly or modified and the short message cannot be sent out, users can check it in the mobile phone information center here. If it is correct, it is no problem to send text messages on your mobile phone.

(2) After the short message is submitted to the communication operator, because the short message sent there is relatively large or very large, the short message is generally sent in line, so there will be a certain delay in sending time, usually tens of seconds or minutes, and if it is slow, it will reach tens of minutes or hours, often during holidays. If there is any bad content in the short message, it will show that the submission failed. Please feedback the relevant results to the user.

(3) If the content of the short message is correct, it means that the short message has been sent to the received number after the communication operator has successfully sent it (that is, there is a feedback report with a successful result, so you need to make a phone call to inquire). Whether you receive SMS at this time may also be related to the mobile phone, and whether the mobile phone firewall and mobile phone housekeeper software intercept it may lead to the failure to receive SMS.

I hope I can solve your problem!
